Understanding SCSI connections
Read this section to determine how to set up your SCSI devices
and whether you need any optional SCSI cables.
2
Daisy chain
The SCSI interface allows you to connect up to seven devices (such
as a scanner, hard disk, CD-ROM, and so on) to the computer, in
what is called a “daisy chain” arrangement. Only the first SCSI
device in a daisy chain is connected to the computer; each of the
other devices is connected to another SCSI device.
SCSI cables
You may need to purchase SCSI cables before setting up your SCSI
daisy chain. Be sure the SCSI cable connectors are suitable for your
hardware, depending on the maker of your SCSI device and SCSI
interface board.
SCSI ID and terminator
Each device has a SCSI ID number: the computer is usually
number 7, and each of the other devices must have a different
number between 0 and 6. Also, the first device and the last device
in the chain (not including the computer) must have a terminator.
No other device can have a terminator, or if a terminator does
exist, it must be turned off or removed.
Setting Up the Scanner
2-9
Setting the SCSI ID number
The scanner's SCSI ID switch is set to number 2 at the factory.
SCSI ID rotary switch
If you add the scanner to a system in which one of your SCSI
devices already has a SCSI ID of 2, change the ID number to an
unused number using the rotary switch. See the table below as a

requires a graphical representation of text to interpret, which usually comes from
a scanned image.
pixel
Short for picture element. Each image is composed of a number of pixels. Pixels
are also counted in units of dots.
port
An interface channel through which data is transmitted between devices.
resolution
Indication of how finely an image is resolved into pixels. Can be measured in
dots per inch (dpi), pixels per inch (ppi), or samples per inch (spi).
scan
An operation performed by the sensor and the carriage. The image is divided
into pixels by scanning.
scanning area
The physical size of the image that can be scanned by the scanner.
SCSI
Small Computer System Interface. This is one method used to connect your
computer to peripherals such as scanners, hard disk drives, CD-ROM drives, and
others.
SCSI ID
The numbers that all devices in a SCSI connection (see daisy chain) use to identify
each other. If the same ID number is used by two devices in the same daisy chain,
the devices cannot operate properly.
terminator
A device that stops electronic signals, and prevents them from proceeding or
returning to other devices. This is necessary to stop a signal from continuously
reflecting between devices.
USB
Universal Serial Bus. A hardware interface for connecting low-speed peripherals
such as a keyboard, mouse, scanner, or printer to the computer.
USB hub
A device that normally provides four Type A sockets to increase the number of
USB ports on a PC.
